Fishers can also choose to release their catch to conserve fish stock.

Undersized, protected, or unwanted fish must be released to the water quickly, carefully, and alive.

Avoid catching undersize fish

Fish usually swim in schools of similar sizes. Change your fishing spot if you are catching undersized fish.

Use larger hooks. Smaller fish are less likely to take large hooks.

Catching and landing

These instructions will help you catch and land your fish to improve their chances of survival.

Choose tackle that will land your target fish in the shortest possible time.

Don’t use tight lines when targeting large fish. This can result in bust-offs and stressed fish.

Avoid long playing times that exhaust fish. Exhausting fish can cause them to die even after they are released alive.

Remove small fish of up to 1 kg from the water by lifting the line.

Remove larger fish using a knotless landing net. Do not use a knotted landing net because they remove protective slime and scales from the fish.

Never use a gaff on fish to be released.

Releasing fish

These instructions will help you successfully release fish.

Unhook fish when they are still in the water.

Handle fish with wet hands. This will reduce damage to the protective slime on the surface of the fish.

Place fish on a cool and wet surface. Avoid hot and dry surfaces.

Move quickly. Reducing time the fish spends out of water will help to reduce trauma to the fish.

Cut the line if a fish is gut or gill-hooked. Hooks are replaceable and you will not damage the fish by removing the hook.

Carefully use fish grips when restraining fish. Avoid grips with inbuilt scales because they hold the fish vertically and can damage the fish.

Hold the fish horizontally and support its body when gently placing it into the water.

Support larger fish with a hand under the head and belly to minimise damage to the backbone.

When photographing your catch

Reduce trauma to your catch when you want to take a photograph with these tips:

Have your camera easily within reach.

Decide early if you want to take a photo and have someone ready with the camera.

Lift the fish horizontally and support its weight at all times. Never lift the fish vertically by the jaw.

Minimise the time the fish is out of the water.

Release the fish gently back into the water as soon as you’ve photographed it.

Measuring and weighing your fish

Measure your fish instead of weighing it. Measuring is much less stressful for the fish.

Use a wet ruler with a stopper on the end to rest the nose against.

Do not use scales that hang the fish by the jaw if you are planning to release the fish. These scales can do damage to jaw and gills of the fish. They also stress the backbone and internal organs of the fish.

Use a sling to support the fish horizontally if you are weighing it.

Use wet hands or a wet cloth to protect the fish eyes and gills.

Returning the fish to the water

Hold the fish gently in the water.

Let the fish leave your hands with a flick of its tail. A strong flick indicates a better chance of survival.

Manually move the fish through the water if it does not move off from your hands. This will help fish that have been over-stressed.

For fish you are keeping

Humanely deal with fish you are keeping:

Place the fish on ice immediately after capture. This will naturally anaesthetise the fish. It will also improve the eating quality of the meat and reduce spoilage.

Spike the fish by inserting a knife or spike in the centre of the fish’s head, immediately behind the eyes. This reduces stress and the fish will give better quality flesh that keeps longer.
